[SOLVED] NetworkManager drops WiFi connection after a few minutes

Hey all,

Recently, NetworkManager started dropping WiFi connection after a few minutes, (works fine on boot), not sure what is going on.

SOLVED: Installing 'networkmanager-noscan' fixed the issue, so it was probably driver-related.

$ systemctl status NetworkManager
